Hi, My next instrument will be my first attempt at fretting. It has a 4.5" wide fretboard. I was interested in the Stew Mac miter box for fretting, but it only goes to 3" wide. Does anyone know if it is built such that it could be modified for accomodating such a wide board? Any other suggestions on ways I could do this without the board? I've seen table saw blades ground for fretting, so I suppose that could be one way. Thanks.
